You write a single sentence to a stranger. You receive someone else's sentence. You may reply once; that reply travels to a third person. The chain lengthens in public view, but identities never attach to links.
The design is deliberately blunt: neubrutalist, loud, impossible to mistake for a chat app. You are not building a relationship. You are adding one link to an anonymous relay.
You can watch how far your message traveled, draw a new inbox item, or join an existing chain from a shared URL. Reporting exists because even anonymous spaces need guardrails.
This is not group chat. It is serial literature written by strangers who will never meet.
